Totem Movie Player

Totem is the media player Ubuntu ships by default. It is based on GStreamer, so other software using GStreamer should have similar results.

Totem does not seem to support SRT files with less than 3 cues and sometimes asks if you want to install the application/x-subrip plugin which it cannot find.
